Should you use Codex, Claude, or ChatGPT? If I’m a business professional wondering TODAY whether to use ChatGPT or Claude or Claude Cowork or Claude Code or Codex, here is what AI I would use under different cost constraints: 1) If I have 500-1000/mo to spare, I’d use Claude Code and Codex, I’d enable Claude Tag in every key Slack channel and use the hell out of it, make it extremely proactive, and I’d use Codex live voice mode every single morning and EOD 2) If I have 400/mo to spare, I’d use both Claude Code and Codex 2) If I have 200/mo, I’d use the Codex 20x plan 3) If I have 100/mo and I view tiny blockers as fun things to push past, I’d use the Codex 5x plan 4) If I have 100/mo and I view tiny blockers as utter hell, I’d use Claude Cowork 4) If I have $20/mo, I’d use Codex and ChatGPT and just focus on scheduled tasks Why Codex over Claude Code? - it’s more complete in features (ex: image gen and voice capabilities) - codex live voice mode is unbelievable - more token-efficient/your money goes farther - feels 2% easier to connect into other tools
